(1) Graphene has good mechanical properties and is one of the materials with the highest strength. At the same time, it has good toughness and can be bent. The reduced graphene modified by hydrogen plasma also has very good strength. After oxidation, functionalized graphene is obtained, and graphite paper made of functionalized graphene will be extremely strong and tough.

(2) Graphene has a good electronic effect, and the carrier mobility at room temperature is about15000 cm2/(v s), which is more than 10 times that of silicon material and more than twice that of indium antimonide (InSb), the known substance with the highest carrier mobility, and the electron mobility of graphene is less affected by temperature changes.

(3) Graphene has good thermal properties and excellent thermal conductivity. The thermal conductivity of pure defect-free monolayer graphene is as high as 5300W/mK, which is higher than that of single-walled carbon nanotubes (3500W/mK) and multi-walled carbon nanotubes (3000 W/MK). In addition, the ballistic thermal conductivity of graphene can reduce the lower limit of ballistic thermal conductivity per unit circumference and length of carbon nanotubes.

(4) Graphene has good optical properties, the absorption rate is about 2.3% in a wide wavelength range, and it looks almost transparent. Large-area graphene films also have excellent optical properties, and their optical properties change with the change of graphene thickness. If a magnetic field is applied, the optical response of graphene nanoribbons can be tuned to terahertz range.

(5) Graphene has good solubility, superhydrophobicity and superhydrophobicity in nonpolar solvents, and can adsorb and desorb various molecules and atoms; Currently with? With the gradual breakthrough of mass production and large-size problems, the pace of industrial application of graphene is accelerating. Based on the existing research results, the first commercial applications may be mobile devices, aerospace, new energy batteries and other fields.

2. The honeycomb flat membrane formed by the hybridization of carbon atoms sp2 is also called monoatomic graphite.
